STAND-POINT FOR TUBULAR WELLS.

SPECIFICATION forming part of Letters Patent No. 492,182, dated February21, 1893.

Application filed October 17, 1892. Serial No. 449,163. (No model.) I

To all whom it may concern.-

Be it known that I, FRANK A. BARRETT, of Newman Grove,in the county ofMadison and State of Nebraska, have invented certain useful Improvementsin Stand-Points for Tubular NVells; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings,which form a part of this specification.

This invention has relation to a new and novel stand point for tubularwells, the object being to provide a point that shall be so arrangedthat a test can be made for water at any point during the process ofboring.

In the accompanying drawings, Figure 1 shows a sectional elevation of astand point with parts broken away, embodying my invention; Fig. 2 is anenlarged sectional view of the sectional washer used in my device, whileFig. 3 shows a top view of Fig. 2.

A represents a tube of suitable size and material,such as is ordinarilyused in boringtubular wells, to thelower end of which is screwed, theperforated tube B which is provided at the lower end with the hollowauger G as is usual in devices of this class.

Held within the auger O is the nozzle plate D, secured by any suitablemeans, provided with the central threaded opening 0, within which isheld the stub pipe E threaded at both ends, and provided with aright anda left hand screw, as shown in Fig. 1. Surrounding this pipe E, which ispreferably a little longer than the tube B, is a sectional washer,comprising the collar F, to which are hinged the washer sections e, 6,6,6, as shown in Figs. 2 and 3. These sections care of rubber, leatheror any other suitable material and are secured between the plates g, g,the lower plate g being provided with a lug 6' having a pin opening,within which the pin 72. is held, and by means of which the sections aremovably secured to the collar F, being held within the ears h, as shown.The sections 6, as will be noticed, are hinged to the collar, and so asto permit a downward or dropping movement of 5c the sections e. Toprevent the sections passing too far upward, I provide the arms it,which are secured to the collar F and act as a stop. The collar F isprovided with an extending bail K, so that the collar which is heldadjustablyupon the tube E, may be raised or lowered, being operated byan ordinary hook secured to a suitable pole.

In the drawings, the sectional washer is shown partly lowered, but whiledrilling this washer is brought upward above the perforations within thetube B, so that while the water might enter the screen tube, it couldnot enter the main tube A.

To test for water while drilling it would simply be necessary to shutoff the water used in drilling, shove down the sectional washer, so thatthe water could enter the screen tube B and rise in the pipe A. If asufficient supply had been found, it would simply be necessary to drop apole hook, engage the bail K, and draw up the washer, the sections ofwhich would close, and so permit a ready removal of the same. The standpipe E could next be removed, by lowering .a pole having a left handedthread within the lower end, which would screw upon the pipe E, andbeing secured, would unscrew the tube from the nozzle P, and so could bereadily removed. In case that the supply proved insufficient, it wouldsimply be necessary to again raise the washer into its first position,until the proper depth had been reached.

The device is noticeable because of its simplicity.

Having thus described my said invention, what I claim as new, and desireto secure by United States Letters Patent, is-

1. In a stand point for tubular wells, the combination with a hollowauger, of a nozzle within said auger, a stand pipe within said nozzle,provided with a right and left handed thread a sectional washer workingupon said stand pipe, comprising a collar, provided with an extendingbail, and a sectional washer hinged to said collar, and a screen pipesurrounding said stand pipe, and secured to said auger, and a supplytube, all substantially as and for the purpose set forth.

2. In a stand point for tubular wells, the combination with the auger C,of the nozzle D, the threaded tube E within said nozzle,

collar F, all arranged substantially as and for the screen pipe Bconnected to the supply the purpose set forth.

pipe A and the auger O, and an adjustable Washer, comprising the collarF having the 5 bail K the stop arms 75, and the sectional Washers 6,held to said collar by means of the plates g, g, the latter beingprovided with the lug e, and held between the ears h of the In testimonywhereof I affix my signature in presence of two witnesses.
